HOT-WATER RADIATOR VALVE.

Specification of Letters Patent.

Application filed May 22, 1909. Serial No.'497,572.

To all whom it mag/ concern:

- Be it known that I, JOHN P. MURPHY, a

citizen of the United'States, residing at Hannibal, in the county of Marion and State of Missouri, have'invented certain new and useful Improvements in Hot-WVateri Radiator Valves, of which the following is a specification, reference being had therein to the accompanying drawing. w

-This invention rel-ates t0 valves for hot water radiators and other places where loose fltt ing and quick operatimrvalves may be used, especially as applied upon bends in pipes.

.The object of this invention is the. production of a valve, which is simple in construction and consists'of a comparatively. small ,number of arts.

Anotherpbjectof this invention is th production of a-novel means for connecting the operating lever to the rotatable-valve stem. a

With these and other objects in view this invention consists of certain novel construc t1ons,- combinatlons and arrangements of parts as will behereinafter-fully described and claimed.

- In the drawings: Figure 1 1s a longitudinal section. of an elbow showing my improved valve applied thereto; Fig. 2 is a transverse section ofthe same; Fig. 3 is an elevation of the valve-stem.

Referring to the drawings by numerals, 1 designates the casing, or elbow, which is provided with an upwardly-extending projection 2 upon the upper portion thereof.

The valve-stem 3 is ,provided upon one side and near the upper edge thereof with a ndtched-portion 9 and a lever-operating member 10 is adapted to fit upon. the upper end of thea'alve-steni 3; said operatinglever 10 is provided with a depending or downwardly-extending portion 11. The casing, or elbow, 1 is provided upon each side ofthe upwardly-extension 2 with an ear 12, which limits the movement of the operatil'iglever 10. It will be obvious that when the I lever is swung to one side, so as to closelthe butterfly valve 5, the depending portion 11 will engage one of the cars 12, and, there fore, the movement of the butterfly valve will be limited." A knob 13 is adapted to be secured tothe operating-lever 10 to facilitate the operation of said lever and said knob 13 is secured to the operating-lever 10 by means of a bolt-member 14, which is provided with a threaded end 15 adapted to wor 1n the threaded aperture 16, formed in t e operating-lever. The threaded aperture 16 is adapted-to register with the notch 9 upon-thvalvestem 3 and the innerend of the bolt-member 14 is adapted to engage the notch 9 and firmly hold the valve-ste'm'3 from independent movement. The lever 10 is provided with a socket portion 17 adapt- Patented A nea, 1910.

ed to receive a bulged portion 18 upon the inner end of the knob 13. It will be obvious that .by.l1aving such a structure the knob 13 willsnugly fit, or engage, the lever member 10 and the knob will be held from any lateral movement. It will also be obvious that the valve-stein will be firmly held in engagement with the operating-lever 10 ture registering with said notch, a knob, a

bolt passing through said knob and working in said threaded aperture and engaging'said notch for firmly securing sald operating the independent rotation of the same, and means formed upon said valve casing'for limiting the movement of said operating handle.

In testimony whereof I hereunto al'lix my signature in presence of twohvitnesses.
